TURNSTILE REGISTERING APPARATUS.

Application filed May 19,

T o all whom t may concern.'

.ie it known that I, SAM li/lfrxnnAcum, a citizen of Russia, residing atChicago. in the county of Cook and State of Illinois, have inventedcertain new and useful Iniprovements in Turnstile Registering Apparatus,of which the following is a specification.

My invention relates to turn stile registering apparatus suitable foruse in situations where it is desirable to obtain accurate informationas to the number of persons passing a certain point, for example,entering` a theatre, public conveyance, or the like.

The principal object of the invention is the provision of a new andimproved apr ratus of the above character that ma lic corr struct-ed andinstalled at a relativelyrv low cost, which will be reliable in itsopera n, and which will be inexpensive to maintain in operativecondition.

The invention has for a further and more specific object, the novelarrangement, construction and combination of parts and deviceshereinafter described and claimed for carrying out the above statedobject and such other objects as will appear from the followingdescription of my invention.

The invention is illustrated in certain pre ferred embodiments in theaccompanying drawing, wherein Fig. 1 is a side view in elevation of aturnstile and registering apparatus constructed in accordance with myinvention, iarts of the apparatus'being shown in section for the purposeof -clearness Fig. 2 is a plan view, partly in section, of

vthe structure shown in Fig. 1'.

Fig. 3 is a view in perspective of an end portion of one of theturn-stile arms.

Fig. 4 is a fragmentary view in elevation of the registering mechanismand its supporting member, and

Fig. 5 isa view similar to 1- 1 illustrating a modified construction. n

Like characters of reference designate corresponding parjts in theseveral figures of the drawing.

Referring first to Figs. 1 to 4 inclusive of the drawing: In thesefigures I have shown an embodiment of my invention as comprising aturn-stile 10, registering mechanism 11, and a flexible member 12-connected with the registering mechanism and so positioned withrelation to the turn-stile that it is enserial No. 562,259.

gaged .intermittently by portions of the turn-stile when the latter is.rota-ted. The turn-stile preferably consists of four radial extendingarms 13 connected at their inner ends in any suitable manner androtatably supported on fixed post 14. The outer ends of the arms arepreferably provided with enlargements 15, each of whirh, is formed withcam surface 16. The registering mechanism 11 may be of any suitable orpreferred malte. For the purpose 'of cenvenience in illustrating the ope'ation of my invention, I have shown in the drawing. a type ofregistering mechanism having an operating lever 17 adapted when forceddownward from the full line position of Fig. r-Itti. the dotted lineposition. to effect a change of one unit in the registering mechanism.The registering mechanism is preferably supported at the upper end of apipe 13. rlie pipe 13 is attached at its lower end to a snitable basemen'iber 19. which in turn is seto the flooring` of the building. Al.ole member 12, preferably, a wire. en tends through the pipe 18 and isattached at one end to the base 19 and at the other end to the lower endof a rod 20, the rod being connected at its upper end to the end of theoperating lever 17. The wire 12 is of such length that it is normallytaut when the op- @ratingl lever 17 is in the full line position of Fig.4. A coiled spring 21 surrounds the rod 20 and is connected at its lowerend to the rod and at its upper end to the pipe 1b and is adapted toreturn the operating lever to its normally full line position andmaintain the wire 12 taut. The pipe 1S is formed with an opening 22 inthe path of travel of the end portions of the turn-stile arms 13 so thatwhen the arms are rotated. for example, by a person passing through theturn-stile in the direction indicated by the arrow in Fig. 2, the camsurfaces 16 at the outer ends of the turn-stile arms will engage thewire 12 and thereby exert a downward pull on the lever 17.

The coil spring 21 effects the return of the lever 17 and the wires 12to their normal position as soon as the wire is freed from itsengagement with the cam surface 16.

In devices of the above character, it is desirable that the arms of theturn-stile be capable'of rotating in one direction only. I preferablyobtain this result by the pro vision of a spring tongue 23 adapted toen-
